Introduction — India’s Seasonal Mood in Winter

As winter deepens across India, the weather today shows a clear contrast between the northern plains wrapped in fog and cold, and warmer, milder conditions in central and southern regions. December marks one of the coldest months of the year, with weather patterns influenced by atmospheric systems like western disturbances, fog formation, cold waves, and temperature differentials between north and south.

❄️ North India: Winter Grip Tightens

🌁 Dense Fog and Cold Morning

In northern states like Delhi, Punjab, Haryana, Uttar Pradesh, Bihar and Uttarakhand, dense to very dense fog continues to blanket the region in the early hours of the day. This is significantly reducing visibility, affecting road travel, flights and daily routines.

  • The India Meteorological Department (IMD) has issued weather alerts for dense fog and cold wave conditions over these regions.

  • Chillier nights and early mornings have pushed temperatures down, with many places experiencing lows around 7–9°C.

🌫️ Transport Impact:
Dense fog is causing flight delays and advisories at airports in Delhi, Varanasi and other northern hubs, as airlines monitor visibility conditions closely.

🌬️ Cold Waves & Winter Alerts

The IMD has flagged cold wave alerts, meaning temperatures are dropping below average for this time of year. The chill has set in over north-central India too, and forecasts suggest these conditions could persist for several days. Business 

🏔️ Himalayan & Hill Region Weather

In the Himalayan belt — Jammu & Kashmir, Himachal Pradesh, and higher reaches of Uttarakhand — there are chances of rain and snowfall, especially at higher elevations, due to ongoing western disturbances.

The combination of snowfall in hills and dense fog in plains is a classic feature of Indian winters this season, creating both scenic beauty and travel challenges.

🌤️ Central & Eastern India

In comparison to the frosty north, central India — including cities like Bhopal, Indore — is likely to experience clear skies with moderate temperatures. Observations show:

  • Daytime temperatures in some central and eastern regions are hovering pleasantly higher than in northern plains. AajTak
